Over at It's About the Money, a writer who goes by the name Hippeaux has stirred up the sabermetric community with a piece in which he argues that WAR (wins above replacement level) doesn't work as well its proponents claim.

I recommend you read the piece, especially if you're at all interested in statistical analysis, or read sites like FanGraphs and Baseball Prospectus. I think Hippeaux raises some fair points and, if anything, it's a reminder that no statistic is perfect.
